I
- switched from Application.LoadLevel to SceneManager.LoadScene because Unity said it was obsolete.
- Added using UnityEngine.SceneManagment;
- Changed using to import.
- Placed the code in different spots since I am unsure where this line is actually supposed to go.
Here's a picture of what I currently have (keep in mind, while it says using I did try import already). The blue lines indicate the other places that I tried placing the code with no luck. 
I’m sure it’s a simple fix, but I am a complete nooob & have only the slightest idea of what I’m doing lol. Thanks in advance for any help.
